CITATION ENCORE
In 2000 the 560 was upgraded again and delivered as the Citation Encore, with Pratt & Whitney Canada PW535A engines and a larger fuel capacity, as well as more interior amenities. The next upgrade was the Citation Encore+, with the addition of even more sophisticated engines and the advanced Rockwell-Collins Pro Line 21 avionics suite. The Encore+ was certified by the FAA in December 2006, with deliveries in the first quarter of 2007.
